Design of analog front-end IC for ECG signal acquisition
摘要
Abstract
A kind of analog front-end IC for Electrocardiogram (ECG)signal acquisition is designed in SMIC 0.1 8μm 1 P6MCMOS mixed-signal process,which includes pre-amplifier,band-pass filter,notch filter of power frequency and post-amplifier.Performance of signal to noise is effectively improved by adopting low noise preamplifier in the analog front-end IC.50 Hz power interference can be effectively rejected by adopting the technique of notch filter.The analog front-end IC achieves an IF gain of 43.44 dB and a passband ranging from 0.0956Hz to 1 07.3 Hz.The analog front-end IC at 0.1 Hz and 1 00Hz achieves the equivalent input noise voltage of 1 5.1 μ V / Hz and 745 nV / Hz respectively.The standby power consumption of the designed analog front-end IC is only 91 2.5 nW with 1 .8 V power supply voltage.Simulation re-sults show that the designed analog front-end IC is suitable for the requirement of ECG signal acquisition.关键词
